Erasing Images
You can either select and erase unnecessary images one by one or erase
them in one batch. Protected images ( = 307) will not be erased.
z Once an image is erased, it cannot be recovered. Make sure you no
longer need the image before erasing it. To prevent important images
from being erased accidentally, protect them. Erasing an image shot in
RAW+JPEG will erase both the RAW and JPEG images.
